Specification of Letters Piatent.

To 'ad whom it may concern:

Be 1t known that l, WILL'IAM SCHWENE, a

-'citizen of the United States, residing at gden, in the county ofBonnev and State of Iowa, haveinvented a certain newand usefulSheet-Metal Wheel, of-which the-following is a specification.

The object `of my invention is to provide an improved wheel of simple'andineXpen-- sive construction that may'beformed complete of sheet metalcut out and shaped by' ldies and that may be quickly and easily asfullyset forth, pointed out in my claims and illustrated in the accompanyingdrawings, in whiehl l Figure 1 shows a side elevation of a completewheel embodying my invention. l'ig. 2. shows a central, sectional lviewof same. Fig. 3 shows a sectional-view on thelline 3-3 of Fig. 1, andFig. 4 shows a sectional view on the line 1 4 of Fig. 1.

` Referring to the accompanying drawings, it will be noted thatl thespoke, felly and tire portions of the wheel are formed of .two

ieces of sheet metal. Each iece com rises a central dish-shaped 'portion10 with thecentral opening to admit the hub portion, hereinafterdescribed, and a number of spoke portions 11 radiating from the part 10,each being curved, as shown in Fig. 1, so that the 4edges of one spokemember will engage and rest upon the corresponding edges of the matingspoke member. At the outer ends of the spoke members is the fiat fellyportion 12 through which rivets 13 are passed for connecting themtogether. Beyond the part 12 the felly members incline away from eachother at 14C and the edges thereof are inclined straight inwardly towardeach other forming the tire portions 15, the adjacent edges ofwhichtouch each other as shown in Figs. 2 and 3.

ln order to firmly brace and reinforce `the inner edges of the `tireportions lo', have placed `abrouml wire or rod 16 withln the spaceinclosed between the felly p ortlons 14 and the tire portions 15, saidwire or rod -hingthe inner; edges of the tire portions @j ffr' beingrm'ly and securely held in a central. positionby the inclined walls ofthe felly portions v14C so that said reinforcing wire or rod does notneed any other fastening device. ln this way the tread portion of thewheel is made substantially as firm and strong as though it were formedvsolid of a single piece of metal. 4'

The hub portion ofthe wheel'is formed of two inner hub members and twoouter hub members. Each inner hub'mernber comprises an annular flange17, apart 418 extending from the flange 17 laterally to engage the inneredge of the part 10, a disk-shaped part 19 to lie 4flat 'against theinner face of the part 10 and a tubular bearing portion- 20 extendinglaterally from the projected beyond the part 10. y

The outer hub members, each comprise an annular flange 21 to lie againstthe outer face of the part 10 and atubular hub member 22 extendedlaterally andi fitting the exterior of the part'20. The outer edge .ofthe part 22 is turned inwardly at 23 to engage the edge of the part 20.l' connect the hub members with the part 10 by |meansof a number ofrivets 24C passed through the parte 10, 19 and 21, as clearly shown in1g. 2. Y y,

All of the parts of my improved'wheel,

part 19 and sheet metal of suitable dies.

r y. Patented Aug. 26,1913. pplication filed April'l, 1967. y Serialho.365,885.

In assembling the' parts, l 'iirst extendthe tubular 'portions 20 of theinner hub members through the sides of the parts 10 and then place-thewire or rod 15 within the felly and tire portion and l finally place theouterV hub members in position and then insert Athe rivets. By thisarrangement of parts, the hub portioninay easily be formed with a smoothinner bearing which does not need to be bored out after the wheel isassembled. These inner hub members by having their'inner portions inengagement with eachother'iirmly brace the v,hub portion of the wheelagainst crushing strains tending to force the parts 10 toward eachother. The outer hub portions serve-' to brace and reinforce the innerones andthey form a double thickness of metal at the point Where great,strains occur and the rivets firmly hold the hub members together andin. proper positions with relation to each' other;

The reinforcing wire 16 arranged Within these parts properly yinposition against crushing stralns and 1n this Way a Wheel of vgreatstrength and durability is provided that is made complete of sheet metaland` Athat is of comparativelylight Weight.

Having thus described my invention, what I claim and desire to secure byLetters wPatent of the United States, therefor isv 1. In asheet metalWheel, the' combination of two sheet metal spokemembers and two she'etmetal hub members, each of said hub members comprising an annularflange, an outwardly extended portion adjacent tothe annular flange, adisk-shaped portion toengage the inner face of the .spoke portion and atubular bearing portion extended laterally to a point beyondl the spokeportion, the'said annular ange por immer tions of the hub members being,r-.n engagement with each other 'and rivets passed through the spokeportions and the said disk portions.

2. In a sheet metal Wheel, the combination of sheet metal spokeportions, 'a pair of inner hub members in engagement with each otherbetween the spoke portions andv haring tubular extensions projectedlaterally beyond the spoke portions, two outer hub members engaging theouter faces of the spoke portions and engagingthe tubular extensions ofthe inner hub members and rivets passed through the outer hub members,the spoke members and the inner hub members.
